Description: Thallus foliose, broad-lobed, heteromerous, dorsiventral, loosely attached, 10-16 cm wide. Lobes rounded at apex, contiguous to imbricate, 10-30 mm wide, with entire to slightly crenulate margins, blue-grey to yellowish grey when dry, dark blue-grey to blue-green when wet, undulate, coarsely reticulate-areolate but without defined ridges, sorediate. Soralia blue-grey, mainly laminal, punctiform at first, but eroding with age and becoming circular; soredia granular. Lower surface with glabrous, whitish patches separated by a pale brown, silky, entangled tomentum, erhizinate or with very sparse, simple rhizines. Upper and lower cortex paraplectenchymatous, the lower cortex poorly developed; medulla white. Apothecia very rare, 1-2 mm across, with a concave, red-brown disc and a verruculose, inflexed, often sorediate thalline margin. Asci 8-spored, fissitunicate, the thickened apex with a K/I+ blue ring, Peltigera-type. Ascospores 1-3-septate, hyaline, elongate-fusiform, 17-23 x 4-7 µm. Photobiont cyanobacterial (Nostoc, the cells in short chains). Spot tests: cortex K-, C-, KC-, P-; medulla K- or K+ yellow-orange, C-, KC- or KC+ pink-orange, P- or P+ orange, UV+ violet. Chemistry: chemotype 1 has usnic and stictic acids plus scrobiculin and sometimes traces of norstictic acid; chemotype 2 lacks stictic acid.
Note: a mild-temperate, suboceanic species found on old deciduous trees and on mossy rocks in humid open forests; formerly more frequent, presently extinct in several parts of the country (e.g. in the whole of the Po-plain), and declining elsewhere, with optimum in old Castanea-stands. A distribution map in Italy was published by Nascimbene & al. (2016). It is included in the Italian red list of epiphytic lichens as “Near-threatened” (Nascimbene & al. 2013c).
Growth form: Foliose, broad lobed
Substrata: bark
Photobiont: cyanobacteria, filamentous (e.g. Nostoc, Scytonema)
Reproductive strategy: mainly asexual, by soredia, or soredia-like structures (e.g. blastidia)
Most common in areas with a humid-warm climate (e.g. most of Tyrrenian Italy)
